Vampire bats are members of the New World Leaf-nosed bats, the Phyllostomidae. All three species of living vampire bats occur in South and Central America. Fossils of three other species reveal that several thousand years ago vampire bats were more widespread.
There are about 900 types of bats worldwide. There are about 40 types of bats found north of Mexico. Bats can be found in colonies; these are called colonial bats. Other bats do not live in colonies, and these are called solitary bats. Most bats found near humans are colonial bats. The little brown bat is commonly found in and around buildings where there is an ample supply of insects nearby.
